Answer:
(328i + 82) / 17
Step-by-step explanation:
`(2i(4+5i)(4-5i))/(4+i)
= (2i(16 - 25i^2)) / (4 + i)
= (2i( 16 + 25) )) / (4 + 1) [Note:- i^2 = -1]
= 82i / (4 + i)
= 82i(4 - i) / (4 + i)(4 - 1)
= 328i + 82 / (16 - i^2)
= (328i + 82) / 17
Answer:
Step-by-step explanation:
We are given the line y=2x+8. It is in slope-intercept form or y= mx+b, where m is the slope and b is the y-intercept.
The slope of the line is 2.
We want to find the equation that is perpendicular. Perpendicular lines have negative reciprocal slopes.
1. Negate
- Negate the slope, or switch the sign
- (+) 2 --> -2
2. Reciprocal
- Flip the numerator and denominator of the slope.
The perpendicular slope is -1/2, so the correct equation must be B.

Fredrick’s data set contains an outlier.
The mean value is about 12.6 home runs.
The median describes Fredrick’s data more accurately than the mean.
Your original inequality is
.. w -2 ≤ 8
The additive property of equality applies to inequalities as well as to equations. You use the additive property of equality to solve this. Add 2 to both sides.
.. w -2 +2 ≤ 8 +2
The purpose of adding 2 is to cancel the effect of subtracting 2. That is, -2+2=0, and w+0 = w.
.. w ≤ 10
The correct selection would be B.
